62 Department of Plant Pathology. 



The new lines of work which the estabHshment of these fellowships has 

 enabled us to get under way are : 



1. Investigations on the uses of sulfur and its compounds as fungicides, 

 with special reference to its use in soil and for dusting. This work is 

 being conducted by Mr. C. N. Jensen and Mr. F. M. Blodgett, under the 

 Herman Frasch Fellowship, established by the Union Sulphur Company, 

 of New York City. It provides for two fellows, and a substantial fund 

 for expenses in conducting the work. 



2. Investigations on the Heart Rots of forest, shade, and fruit trees, 

 conducted by Mr. W. H. Rankin, under the John Davey Fellowship, 

 established by the Davey Tree Expert Company of Kent, Ohio. 



3. Investigation of the effect of cement dust on the setting of fruit, 

 injury to foliage, etc., conducted by Mr. P. J. Anderson, under the 

 Ten Broeck Fellowship, established by Mr. Wessel Ten Broeck, Hudson,

 trees, with special reference to the New York apple tree canker and its

5. Investigations on the diseases of fruit and fruit trees, with special

 compounds, alone or combined with various arsenicals. These investi- 

 gations, which are to begin next spring, are to be conducted by Mr. 

 George A. Osner and associate, under a fellowship established by the 

 Betheny-Batavia Fruit Growers' Association, Batavia, N. Y. These

 other field crops have been undertaken during the past summer on the 

 Chemung county fair grounds, near Horseheads, N. Y. The work, which 

 was conducted by Mr. I. C. Jagger, is under the joint direction of the 

 departments of Plant Pathology and Plant Breeding. 



EXTENSION. 



The extension activities of the department may be classified as follows : 

 I. Teaching. — During the past college year, a course in plant diseases 

 was offered as usual to men in the Winter Courses. Farm Botany, which 

 does not naturally belong to this department but which we have hereto- 

 fore given, was not offered this year. Because of our crowded condi- 

 tions, it was possible to give only lectures in the plant disease course.
